P2131 2009 Ford Fusion Code - Throttle/Pedal Position Sensor/Switch 'F' Circuit

Quick Answer

The Accelerator Pedal Position (APP) sensor is an input to the Powertrain Control Module (PCM) and used to determine the amount of torque requested by the operator. Common causes include Faulty Accelerator Pedal Position (APP) Sensor, Accelerator Pedal Position (APP) Sensor harness is open or shorted, Accelerator Pedal Position (APP) Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2131 2009 Ford Fusion Description

The Accelerator Pedal Position (APP) sensor is an input to the Powertrain Control Module (PCM) and used to determine the amount of torque requested by the operator. There are 2 pedal position signals in the sensor. Both signals, APP and APP2, have a positive slope (increasing angle, increasing voltage), but are offset and increase at different rates. The 2 pedal position signals make sure the PCM receives a correct input even if 1 signal has a concern. The PCM determines if a signal is incorrect by calculating where it should be, inferred from the other signals. If a concern is present with one of the circuits the other input is used. There are 2 reference voltage circuits, 2 signal return circuits, and 2 signal circuits (a total of 6 circuits and pins) between the PCM and the APP sensor assembly. The pedal position signal is converted to pedal travel degrees (rotary angle) by the PCM. The software converts these degrees to counts, which is the input to the torque based strategy. The accelerator pedal position (APP) sensor fault flag is set for sensor 3 by the Powertrain Control Module (PCM), indicating the signal is out of the normal self-test operating range.

Frequently Asked Questions about P2131 2009 Ford Fusion Code

1. What are the common symptoms of OBDII code P2131 on a 2009 Ford Fusion?

- Common symptoms include reduced engine power, hesitation or stalling while driving, and the vehicle going into "limp mode" to protect the engine.

2. What causes the OBDII code P2131 on a 2009 Ford Fusion?

- The code is typically triggered by a faulty throttle position sensor, pedal position sensor, or wiring issues in the 'F' circuit.

3. How can I diagnose the throttle/pedal position sensor/switch 'F' circuit issue on my 2009 Ford Fusion?

- Use a diagnostic scanner to read the code, inspect the wiring harness for damage, and test the throttle and pedal position sensors for proper operation.

4. Can a dirty throttle body cause the OBDII code P2131 on a 2009 Ford Fusion?

- Yes, a dirty throttle body can cause erratic sensor readings and trigger the code. It's recommended to clean the throttle body as part of the repair process.

5. Is it safe to drive my 2009 Ford Fusion with the throttle/pedal position sensor/switch 'F' circuit issue?

- It is not recommended to drive the vehicle with this issue as it can lead to unsafe driving conditions and potential engine damage. Have the problem diagnosed and repaired promptly.

6. How much does it typically cost to repair the throttle/pedal position sensor/switch 'F' circuit issue on a 2009 Ford Fusion?

- The cost of repairs can vary depending on the exact cause of the issue, but it may range from $200 to $500 including parts and labor.

7. Can I reset the OBDII code P2131 on my 2009 Ford Fusion by disconnecting the battery?

- While disconnecting the battery may clear the code temporarily, it is not a permanent solution. The underlying issue causing the code needs to be addressed to prevent it from reoccurring.

8. Will the check engine light turn off automatically after repairing the throttle/pedal position sensor/switch 'F' circuit issue on a 2009 Ford Fusion?

- In most cases, after the repair is completed and the issue is resolved, the check engine light should turn off on its own. If it doesn't, you may need to clear the code using a diagnostic scanner.

9. Are there any recalls or technical service bulletins related to the OBDII code P2131 on a 2009 Ford Fusion?

- It's recommended to check with a Ford dealership or visit the National Highway Traffic Safety Administration (NHTSA) website to see if there are any relevant recalls or bulletins for this specific issue.

10. Can I perform the repair for the throttle/pedal position sensor/switch 'F' circuit issue on my 2009 Ford Fusion myself?

- While some DIY enthusiasts may be able to tackle this repair, it's recommended to have a professional mechanic diagnose and fix the issue to ensure it is done correctly and safely.
